| titleOfInvention | Preparation method of high-strength immobilized microspheres for embedding thiobacillus denitrificans |
| abstract | The invention relates to a preparation method of a high-strength immobilized microsphere embedded with thiobacillus denitrificans, which comprises the following steps of (1) obtaining an aqueous solution of thiobacillus denitrificans; (2) adding polyvinyl alcohol and sodium alginate into water, heating to change the polyvinyl alcohol and the sodium alginate into viscous liquid, and adding volcanic rock powder into the viscous liquid after cooling to obtain a volcanic rock powder modified polyvinyl alcohol composite sodium alginate embedding agent; (3) grinding oyster shell into oyster powder; (4) mixing the oyster powder obtained in the step (3) and the wet thalli obtained in the step (1) to prepare an embedding body for embedding; (5) uniformly mixing the embedding body and the embedding agent, and dropwise adding the embedding body and the embedding agent into a cross-linking agent for reaction until the mixture is solidified into a spherical shape to obtain immobilized microspheres; (6) obtaining the high-strength immobilized microspheres embedded with the thiobacillus denitrificans. The immobilized microspheres have high mechanical strength and elasticity, the service life of the hydrogel is prolonged, and the immobilized microspheres have high practical application value. |
